Frequently Asked Questions
Q: What components are included in the lift cylinder overhead kit 00591-01185-81?
A: This overhead kit includes piston rod seals, gland seals, backup rings, wear rings, and hardware necessary to rebuild or repack the overhead tilt cylinders on Toyota lift trucks. The kit is designed to restore cylinder performance and eliminate leakage without removing the cylinder from the truck frame.
Q: Which Toyota lift truck models can use this overhead kit?
A: Verify compatibility with your truck model year and mast type. This kit is engineered for specific overhead tilt cylinder bore sizes and rod diameters. Confirm your lift truck model against OEM specifications before ordering. Contact our parts team with your equipment serial number for the correct kit version.
Q: What are the symptoms that an overhead kit rebuild is needed?
A: Signs include hydraulic fluid leaking from the cylinder rod end, slow or jerky tilt operation, loss of tilt function in one direction, visible corrosion or scoring on the rod surface, or inability to maintain tilt angle under load. If the truck tilts forward or back uncontrollably, stop operation immediately.
Q: Can I install this kit without removing the cylinder from the truck?
A: Yes, the overhead kit can be installed with the cylinder in place by removing the gland nut and piston rod end. This approach saves downtime and does not require a press. You must completely depressurize the system before disassembly. If the rod is scored or bent, the cylinder must be removed and replaced.
Q: What is the expected service life of this kit?
A: Seals and wear components typically last 1200 to 1800 operating hours in normal duty. High-cycle operations or cold storage environments may reduce life. Use only OEM fluid type and maintain system cleanliness to maximize seal life. Replace the complete kit if any seal fails; do not attempt partial repairs.
